Yoshihide Ito sometimes makes ¥40,000 a day selling organic vegetables from the tailgate of his vehicle in a space he rents in front of a beauty parlor when it isn't open for business.

"Won't you have some rare organic vegetables?" he calls out from the corner of a street lined with fashionable restaurants in Meguro Ward, Tokyo.

His vehicle was laden with about 40 different kinds of vegetables, including purple carrots, arugula and Brussels sprouts, all grown free of chemical fertilizers.
